Why State Law Governs, and What It Means for Your Claim
When an injured rider asks what the deadline is, the honest first answer is that it depends on the state. Limitation periods, the deadlines for filing personal-injury and wrongful-death claims, are set by state law and differ from state to state, as do the rules on when the period starts and what exceptions apply. Some claims against public entities carry separate notice requirements, and some states limit how long after a product's sale a product claim may be brought. For someone in this position, the state where the crash happened, and whether a public entity or an older product is involved, can change which deadline applies.
Fault rules vary too, and they matter if anyone argues that the injured rider shared some of the blame. Under comparative fault, what an injured person may recover is reduced by their own share of responsibility. Some states apply that rule in pure form. Others bar recovery once the injured person's share passes a set threshold. A few still follow contributory negligence, which can bar recovery for any share of fault. The same facts can lead to different results across state lines. Wrongful-death rules, including who may bring a claim and what damages are available, differ as well. The site's state pages, such as the Texas ATV and UTV page and the California ATV and UTV page, set out those states' rules from their official texts.
Federal law plays a narrower role. Under 15 U.S.C. § 2089, Congress directed the Consumer Product Safety Commission to adopt the ANSI/SVIA voluntary standard for four-wheel ATVs as a mandatory safety standard. Once it took effect, the statute made it unlawful for a manufacturer or distributor to import or distribute a new ATV in the United States unless the ATV complies with the standard, is subject to an approved ATV action plan and bears a label certifying compliance, and the manufacturer or distributor complies with that plan. The same section bars new three-wheeled ATVs from import or distribution until a mandatory standard for them is in effect.
That standard is codified at 16 C.F.R. part 1420; 16 C.F.R. § 1420.1 states that the part prescribes requirements for all-terrain vehicles. Under 16 C.F.R. § 1420.3, a new ATV manufactured before January 1, 2025, must comply with ANSI/SVIA 1-2017, and one manufactured on or after that date must comply with ANSI/SVIA 1-2023, except that for the owner's manual section it continues to follow the 2017 version.
These provisions apply to ATVs as 15 U.S.C. § 2089 defines them: a straddled seat and handlebars, on three or four wheels. This page does not apply them to UTVs or side-by-sides. Whether a federal standard bears on a state-law claim is itself a question of state law and the facts; the site's page on CPSC ATV safety standards covers the standard in more detail. Which state's law applies, and what its rules mean for a particular crash, is exactly what a case evaluation addresses.
